"fuseful" Improvement in Ca1culating-'- \Ia- Be it known that I, HYMAN ELI GO D- BERG, a citizen of the United States, residing "at Chicago', in the county of Cook and State have invented a certain new and chines, tion.

My invention relates to improvements in calculating machines and more particularly the totalizers thereof, and has for its object of which the following is a specificathe rendering of such totalizers more reliable in their work. This is accomplished chiefly,

through the novel construction of the carrying wheels and the mountings thereof, as will hereinafter appear.

In some of the totalizers now known in the art, for example in the totalizrs shown in my Patents 710,772, issued October 7, 1902, and 741,961, issued October 20, 1903, the carrying from one carrying wheel to another is done through the medium of a carrying pinion. In order to permit the operation of those totalizers it was necessary to release the carrying wheel at the operating point from the next lower one, This was accomplished by swinging the intermediate carrymg pinion out of mesh with its two cooperating carrying wheels. In'order to revent tlns carrying pinion from being acci entally rotated while thus unmeshed, a locking'bar ordetent was provided so constructed and located as to, engage the carrying pinion "while the latter was in unmeshed osition.

But it was found in practice that if t e parts were not carefully made, the carrying mion would, in spite of said bar sometimes e rotated out of place so that when efiort was made to have it remesh with the carrying wheels the teeth would jam and cause trouble. As the result-of my present invention this difficulty is obviated, for in my new construction all of the wheels, swinging and stationary, are kept continuously under control so that there is no opportunity for thern to developed, that is,

view of the swingin mounted -u shown one carrying wheel acts directly upon the next without any intermediate piece.

In the accompanying drawings igure 1 is a front elevation and Fig. 2 an end ele'va: tion of a ty ewriter andcalculating attachment inclu ing a totalizer embodying my invention. It will be understood however, that the invention is equally applicable to independent machines. Fig. 3 is av front elevation of the totalizc'r and the cooperating portion of the differential mechanism, the two trate their. construction and relationship. Fig. 4 is a diagrammatic front view of some of the parts of the totalizer, the parts being arranged inla plane and slightly separated. Fig. 5 is an end view of the parts shown in Fig. 4. Figs. 6', -7, 8 and 9 are sectional elevations showing the totalizer and master wheel. Figs..6, 7 and 8 illustrate .more particularly the operation of what I shall term the' direct swingholders and partsm'ounted therein and Fig. 9 thefindi rect swingholders and parts mounted therein. Figs. 8 and 9 are to a certain extent fragmentary as they emit, for the sake of clearness, some of the parts shown in Figs. 6 and 7. Figs. 10 and 11 are front and side views of the indirect swingholder and operating arm. Figs. 12 and 13 are front and side views of the direct swingholder and parts mounted thereon.v Fig. l i'is a side detent located at the units end of the tota 'zer. view of three carrying wheels showing their relative positions when in gear with each other. .Figs. 16 to 20 inclusive show the component parts of the carrying wheels. The views are taken respectively on the planes.l6-16, 1717 1818, 19-19 and- 20-20, Fig; 15.

Referring to the drawings, the typewriter has a stationary framework 21, a carriage 22 adapted to travel thereon, and typewriter keys 23. The differential mechanism 24 is on the framework 21 and is con nected to t e numeral keys of the ty ewriter in any suitable manner. .Said d1 erential mechanism operates the settim or 'master wheel 25 mounted upon the shaft 26, secured to the stationary framework of the machine. The typewriter selected for illust'ration is a Remlngton, and the differential mechanism is similar to the one described in my Patent 710,772, issued October 7, 1902;

being slightly separated to'betterillus.

Fig. 15 is a front but as typewriters and diil'erential mecharb .isms of this kind are well known. in the art no detailed descriptionof them is necessary here. It is snfiicient to say that the construction is'such that when a numeral key is depressed the master wheel will be rotated the proper amount, depending upon the figuration of said extremit -wheel e ect it whenever t value of the numeral, and the carriage will travel one letter space. In the present mech anism the depressing of a key produces another; effect; tosvit, the oscillatoryhiovement of the operating arm 27, pivotally supported upon" the stationary shaft 28;- The construet'lon and operation of the arm. is such that normally, when-the master wheel is at rest, 'the arm will occupy th e'position shown in Figs. 6 and 8,, that is, outof engagement with the swingholders,.but during the rotation of. the master wheel the arm will occupy the position shown in Fi s. 7 and 9 and will hold whichever swingholder happens to be in cooperative relation at the time, in the position shown in Figs. 7 and 9. Various means may be employed for producing this oscillatory movement of the operating. arm 27 and an advantagous construction is described in detail in the above mentioned patent. A

member .Iearing a similar relationship to the master wheel is also shown in each of m issued patents hereinabove mentioned. In the present construction however, the oscillatory moveinent'of the o crating arm 27 is produced by the-master W eel itself cooperating with a tension spring 29 which tends to force the V shaped extremity of the extension 27' ofsaid arm toward said master wheel. On account of the V shaped conthe teeth of the e wheel rotates, and thus move the arm tp/the position shown in Figs. 7 and 9. But as soon as the master wheel stops rotating said V shaped extremity .support the shafts 34, 35, 36, 37 and 38.

tends to re'e'ntcr between the teeth of the master wheel, which permits the spring 29 to retract the "operating arm 27 and return it to the normal position shown in Figs. 6 and 8.

The totalizer, with which my present invention is more particularl concerned, is mounted upon a truck 30 which is ada ted to slide upon a horizontal bar 31 secured to the stationary framework of the machine. An arm 32 extends from the typewriter carriage to the truck and thus causes the latter to travel in unison plates 33 which constitute the side walls of the totalizer are fastened to the truck and On the shaft 34 are loosely mounted a series of gear wheels 40;; which are adapted to be enz-wheel. To facilitate gaged oneafterthe 0t er by the master wheel 25 as the totalizer travels past said master description these wheels 40 maybe termed receiving wheels. The function of the receiving wheels is to transmit rotary motion from the master wheel 25 coking portion 47 on the coo with said carriage. The

state.

to the carrying wheels and to the fi ure wheels 41. The particular means by which this rotary motion is transmitted to the fig ure wheels is immaterial but in the present case each figure wheel is rovided with a gear 42 fastenedto its side w iich is driven by the transmission gear wheel 43 loosely mounted on shaft 35 and driven by its respective rcceivin wheel 40.

ll wi I now describe the construction of the carrying wheels and will then describe the means by which they are supported and operated. These -form important features of my invention.

The construction of the carrying wheels themselves is bestshewn in Figs. 15 to 20 inclusive. Each wheel comprises four rincipal portions 45, 46, 47 and 48. The lbcked portion 45 is adapted to cooperate with the crating carrying wheel, and the carried portion 46 is adapted to cooperate with the carrying portion 48 on the cooperating carrying wheel. The pertions 45 and 46 are connected to the portions 47 and 48, preferabl by means of the spacing sleeve 49. By p're erence these parts are all integral although of course they may be made separately and afterwards brazed, )inned o otherwise rigidly fastened together. Vhen the carrying wheels are inoperative relation a carrying wheel of any given order will coiiperate with the carrying wheel of next lower order and also with the farming wheel of next higher order. The relationshi is such that when. the parts are in norma position the portions 45 and 46 of any given carrying wheel will cooperate with the portions 47 and 48 of the carrying wheel of next lower order and the portions 47 and 48 01 said given wheel will cooperate with the portions 45 and 46 respectively of the carrying 'whee hef next higher order.

The construction of the locked and locking portions of the carrying wheels is best shown in Figs. 17 and 241- They are constructed upon the principle of the Geneva gear which is well known. The locking portion 47 consists of a disk having a recess 47 at the carrying point. The teeth of the locked portion 45 are so shaped as to fit over said disk and prevent rotation of said locked portion except when recess 47 comes around and allows one of said teeth to enter it. The construction of the carried and carrying )ortions 46 and 48 respectively, are best s -own in Figs. 16 and 19. The carrying portion 48 has a carrying t00th '48 adapted to the teeth of the carried it and thus carry.

As already mentioned each carryin wheel meshes directly with the carrying w} eel of next higher order. ing wheel is about to be rotated it must first be released by the carryin wheel of next lower order but-must remain in mesh with portion 46 to rotate engage 30 in the drawings) in 40 position l toward each other.

the carrying wheel of next higher order or-' ticular construction selected for illustrating the invention, said swingholders areof two kinds which for convenience will be referred to as the direct swingholders 52, shown speciallyin Figs. 12 and 13, and'the in- 5 'direct swingholders 53 shown separately in Figs. 10 and 11. I thus name t cause the direct swingholders are 0 erated directly from the operating arm 27 w ich cooperates with the extension 52 of thedireet em be- 0 swingholder while the indirect swingholders are operated indirectly from said' arm 27 through the. agency of the levers 54. The holders 52 and 53 are arranged in two groups mounted so as to swing through a limited are 5 about the shafts 38 and 37 respectively.

The direct swingholders 52 have extensions 52 and .the levers 54 have extensions 54 adapted to be fastened to s rings 55 to -be influenced by them to rotate when viewed as i an anti clockwise direction. Thesprin'gs 55 arefastened to the rod 56 secured to the side walls 13. The levers 54 which are pivotally supported on shaft 38 have teeth 54: engaging teeth 53 in the indirect swingholders so that when said levers swing in one direction the holders 53 will swing in the opposite direction about the shaft 37. The construction is such'that the ,springs 55 tend to hold the swingholders in to hold the carrying wheels in mesh with each other A stop bar 57 which is se-. cured in the side walls 13 is provided for engaging the extensions 52 'and levers 54 to limit the movement of the carryingwheels springs 55 from exerting too muchpressure in holding the carrying wheels in mesh. The direct and indirect swingholders alternate with each other laterally so that as the totalizer moves past the master 'wheel 25 first a direct and then an indirect swingholder will come into'operative relation with the operating arm 27. The arrangement of the parts is such that when any figure wheel is in geared connection with the master wheel the swingholder supporting the carr ing wheel of next lower order will be in position to be acted upon by the operating arm 27.

I will now describe the gearing by whieh motion is transmitted from the receiving wheels to the carrying wheels. The gzarried portion 46 of each carrying wheel i acted upon not only by the carrying ortion 48 of the codperating carrying wheel ut by a gear 5 wheel 58 loosely mounted upon a pin 59 in each of the swingholders 52 and 53. The gears 58 in the indirect swingholders are permently in mesh with and are driven by the I gear wheels 62 which are independently rotatable upon shaft 37. There is awheel 62 for each of the receiving wheels 40 and they remain permanently in mesh therewith. The gear wheels 58 in the direct swingholders 52 are permanently in mesh both with the portions 46 of the carrying wheels in said direct swingholders and with the ,gear wheels 63 which .are independently rotatable upon shaft 38. The wheels 63 are equal in number to the direct swingholders and are permanently in'mesh with the wheels 62.

As best shown in Fig. 4:, which is a developmentof the parts slightly separated for the sake of illustration, it will be seen that those particular wheels 62 which are in mesh with the wheels 63 are not in mesh with "the wheels.58 of the indirect swingholders. Also that those wheels 62 which are in mesh with the wheels 58 in the indirect swingholders are not in mesh with the wheels 63. Wherefore the various trains of gearing associated with the direct and with the indirect swingholders and shown in Figs. 8 and 9 respectively are completely independent and consequently the carrying wheels mounted uponthe direct and indirect swingholders are not in gear connection with each other through the train I of gearing comprising the wheels 58, 63, 62 and 58. In other words, unless the carrying wheels are in actual direct mesh with each other there islno gear connection between them. Of course the carrying wheels are directly in mesh with each other when in 0 erative'posit'ion shown in Fig. 6. It will t us beseen that each carrying wheel whether mounted upon a direct swingholder or upon an indirect one is always in gear connection with its codperating receiving wheel 40. Consequently, if said wheel 40 be held (as hereinafter explained) then the. position of This prevents the the 006 crating carrying wheel will always be perfect y definite whether the swingholder in which it is mounted be in its approached position or in its retracted, position or intermediate between the two. In order to hold the wheel 40 stationary there is mounted upon theiramework 21 immediately to the right of the master wheel 25 a fixed late 67 as best shown in Figs. 1 and 3; Yv henever the master wheel engages any receiving wheel 40-the holding plate 67 engages and holds the wheel 40 of next lower order. The latter wheel is the one'which is in mesh with the carrying wheel mounted upon that particular swingholder which is temporarily in engagement with the operating arm 27. Thus when the master wheel rotates, and the operating arm 27 operates the swingholder,

the carrying wheel mounted upon said readily into mesh. with each other.

but While retracted will remain in mesh with its own held receiving wheel ell) and tints it will he noted that the carrying wheels.

are epicyclicslly connected with the wheels 62 end 63 mounted upon the aides?! and 38 about which the swingliolders swing. More over the number of the csrryiiw Wheels and Wheels 62 0 :63 substantially equal. Conseqnently hen the swingholders ere swung" about tlio respec tive axes 37 or 38 the carrying wheels ,Will move straight toward or awsy from each other, consequently will always come This is one of the important characteristics of this invention for as :1 result of it there is no possibility for the carrying wheels to jam tooth upon tooth when the Withdrawn carrying wheel is :tpproaching its mates.

Means is provided for normally holding the units wheel locked. This consists of s dog 65 ivotslly supported on the shaft and. in. uenced by one of the springs 55. Said dog has s tooth for engaging the portion so of the units carrying Wheel as shown in Fig. 14.

In operation, ivhen e numeral key is'depressed the master Wheel rotstes and drives the figure wheel corresponding to-the ordinal place which the numeral occupies in the number to be added. The rotation of the master wheel causes the ejection of extension and consequently movement of arm 27 to engage the swingholder supporting the carrying Wheel of next lower order. As soon as the master Wheel has completed. its rotation the arm 27 is returned by its spring 29 to normal position shown in Figs. 6 and 8 and said swingholder is returned by its spring to normal position, with its carrying Wheel in mesh with its two mating or cooperating carrying wheels. if the amount of rotation of the master Wheel has been such as to cause the operated figure Wheel to rotate beyond the Zero mint the carr 'in tooth 48 on the corresponding carrying Wheel will have engaged one of the teeth of the carried portion 46 of the next higher carrying wheel and will consequently have rotated snid next higher carrying wheel, which rotation will be trans mittcd to the figure wheel of next higher order through the intermediate connecting gear wheels.

It will be seen from the ohove description that in my totalizerthe csrrving Wheels ongage with each other directly Without any intermediate wheels. As a result, not only is back lash avoided'lout the mechanism is correspondingly simplified, It will also be seen that a carrying Wheel though it may be withdrawn from and he dut'ot en egemcnt- With its cooperating carrying wheels, *ill be positively prevented from rotating licczmseteeth in portions oi new it will, through Wheels 58, 63, 52 and 40 be locked by the locking plate 617.
